Product Description

Overview

The KJ3223X1-BK1 AI 16-Channel 4–20mA HART Card from Emerson DeltaV is engineered for hazardous environments, providing precise analog input measurement and HART communication for advanced process control. This module supports Zone 2 and Class I Division 2 hazardous areas and offers robust electrical and environmental performance for reliable operation in industrial systems.

Installation and Safety Notes

• Field power, either local or bussed, must be removed before installation or removal

• I/O loop assessment required for all energy-limited nodes before connection

• Module cannot be inserted or removed while system power is energized

• Rotary keying system ensures correct alignment between I/O cards and terminal blocks

• Terminal blocks must be keyed to the I/O card they serve

• Refer to documentation:

• 12P5404 “DeltaV™ Scalable Process System Zone 2 Installation Instructions”

• “DeltaV™ S-series and CHARMs Hardware Installation” manual

Maintenance and Calibration

• No user-serviceable parts

• Disassembly is prohibited

• Calibration is not required

Application Scenarios

Ideal for high-density analog input measurement in hazardous zones, integrating 16 channels of 4–20 mA HART signals into DeltaV systems for chemical processing, energy, and oil & gas facilities.

Frequently Asked Questions (FAQ)

Q: Can this HART card be removed while the system is powered?
A: No. Removal or installation requires the system to be powered down unless the area is non-hazardous.

Q: Is calibration required for operation?
A: No. The module does not require calibration and has no user-serviceable parts.

Q: How does the keying system prevent installation errors?
A: The rotary keying system ensures the terminal block is correctly matched to the corresponding I/O card.
